INTRAOPERATIVE IMAGE REGISTRATION BY MEANS OF REFERENCE MARKERS

摘要

A method for incorporating tomographically obtained image data from a patient into a system for surgical planning and/or intraoperative navigation involves tomographic image data or image data obtained by X-ray recordings from at least one defined body area of the patient by at least one first recording appliance, wherein a first reference body having at least one surface is arranged on the patient and is recorded by the first recording appliance at the same time. The recorded image data representing the first reference body are compared with known geometric data from the first reference body in order to obtain distortion information. The recorded image data are equalized by a computation unit based on the distortion information to obtain equalized image data which have further image data from the same body area superimposed to obtain superimposed image data that is presented on a display.

1. A method for including image data of a patient in a system for operation planning and/or intraoperative navigation, comprising the following steps:
recording tomographic image data or image data obtained by x-ray technology of at least one defined body region of the patient by least one first recording device suitable therefor, wherein a first reference body with at least one surface is arranged at the patient and also recorded by the first recording device; comparing the recorded image data representing the first reference body with known geometric data of the first reference body for obtaining distortion information, rectifying the recorded image data by a computer unit on the basis of the distortion information in order to obtain rectified image data; superposing the rectified image data with further image data of the same body region of the patient in order to obtain superposed image data; and depicting the superposed image data on a display.
